Vulnerability Details CVEID: CVE-2018-1904 DESCRIPTION: IBM WebSphere Application Server could allow remote attackers to execute arbitrary Java code through an administrative client class with a serialized object from untrusted sources. CVSS Base Score: 8.1 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 152533 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H) CVEID: CVE-2018-1840 DESCRIPTION: IBM WebSphere Application Server could allow a remote attacker to gain elevated privileges on the system, caused when a security domain is configured to use a federated repository other than global federated repository and then migrated to a newer release of WebSphere Application Server. CVSS Base Score: 6 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 150813 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:C/C:L/I:L/A:L) CVEID: CVE-2018-1901 DESCRIPTION: IBM WebSphere Application Server could allow a remote attacker to temporarily gain elevated privileges on the system, caused by incorrect cached value being used. CVSS Base Score: 5 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 152530 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:L) CVEID: CVE-2018-1926 DESCRIPTION: IBM WebSphere Application Server Admin Console is vulnerable to cross-site request forgery, caused by improper validation of user-supplied input. By persuading a user to visit a malicious URL, a remote attacker could send a specially-crafted request. An attacker could exploit this vulnerability to perform CSRF attack and update available applications. CVSS Base Score: 4.3 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 152992 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N) CVEID: CVE-2018-1957 DESCRIPTION: IBM WebSphere Application Server could allow sensitive information to be available caused by mishandling of data by the application based on an incorrect return by the httpServletRequest#authenticate() API when an unprotected URI is accessed.
